Metrowerks bundled PowerPlant and its successor, PPx, for years with the CodeWarrior compiler suite. The forward-looking PPx is geared toward Carbon development under Mac OS X. Though Metrowerks has left the Macintosh market for CodeWarrior, an open source community continues to maintain it.

PowerPlant's ChiefArchitect is GregoryDow?, who also wrote the earlier TCL ("THINK Class Library") framework bundled with Lightspeed/THINK/Symantec C and C++. He now works for Adobe following the Macromedia acquisition.
